Methods and systems for implementing and operating multiple-input and multiple-output (MIMO) antennas for radio telecommunications

An antenna comprising:

• a planar dielectric substrate;
• a primary conductive area on a first surface of the planar dielectric substrate, wherein the primary conductive area has a shape defining:
• a first region of the first surface bounded by at least a portion of the primary conductive area, and a second region comprising a remaining portion of the first surface;
• a first secondary conductive area on the first surface, wherein the first secondary conductive area lies in the first region of the first surface;
• a second secondary conductive area provided on the first surface, wherein the second secondary conductive area lies in the second region;
• a ground plane on a second surface on other side of the planar dielectric substrate;
• a first signal connection connected to the first secondary conductive area;
• and
• a second signal connection connected to an edge of the primary conductive area adjacent the second secondary conductive area.
